We have been travelling a lot this summer. I think the girl who feeds him must be scared and he knows it because he attacks and bites hard when I try to change food or water sometimes when I have him out if the cage. I know it must be puberty . He is a year and 3 months old. I am ignoring the bites and holding him when he is being good. It is very Jeckyl and Hyde ish. Help would be appreciated if you have been through this. I did pet him day before yesterday and he liked it after he calmed down.
